AI Readability vs eReadable

AI Readability is a web checker for English text aimed at writers, editors, and content teams. It measures how readily people can read text and how easily AI systems can parse and reuse it. The checker returns a score from 0 to 100 covering Sentence Clarity, Structural Organization, Entity Consistency, and Answer Readiness. It also offers a short illustrative rewrite, rather than a complete edit. Scoring runs entirely in the browser, so pasted text is not sent to a server during the check. The site says the tool uses transparent heuristics without a model call, server, or crawl, and requires no signup. English is the only supported language. Selecting “Continue in Textorum” sends the text to Textorum through the URL. The maker describes the score as a proprietary diagnostic framework, not a validated scientific instrument, and says no readability tool can promise citations or rankings. The free plan costs nothing.

eReadable is a free web-based writing tool for examining readability and adapting text to a target reading level. Its checker reports readability scores and grade levels, then flags difficult lines for review. The Text Simplifier rewrites dense passages in clearer English while aiming to retain required meaning. The Plain English Checker identifies jargon, legalistic wording, vague phrases, and passive voice, suggesting clearer alternatives. A Reading Level Converter supports grade and CEFR targets such as Grade 5, Grade 8, Grade 10, B1, and B2. The Sentence Rewriter offers clearer, shorter, or more direct versions for individual lines. eReadable combines formulas, structural checks, and task-specific rewriting, including Flesch Reading Ease, Flesch-Kincaid, Gunning Fog, and SMOG. It accepts text input and includes grade-level analysis, sentence-complexity checks, and plain-language rewrites. Automated output still requires review for meaning, terminology, factual accuracy, and legal accuracy.
